If the dryer still heats, but the drum does not turn, this is commonly the symptom of a broken dryer belt.

If the model number is correct, installing a new dryer belt for this dryer involves the following steps:

1. UNPLUG the dryer and remove the lint screen.

2. Remove the two screws that were under the lint screen and lift the top panel. NOTE: You should be able to see the dryer belt tightly wrapped around the drum. If the belt isn't present, its a good sign that it has snapped and may be laying in the bottom of the cabinet.

3. Unplug the door switch conector plug and any ground wire that may be installed on the casing.

4. Locate the two screws that hold the front panel in place. There should be one screw on each side in the cabinet interior.

5. With the door shut, lean against the front panel and remove the two screws that hold it in place. Once the screws are removed, grasp the front panel at the top center and lift straight up to remove.

You should now have complete access to the dryer interior. If the belt is broken, this may cause the idler pulley (tensioner) to come loose. This is normal with no tension on the pulley to hold it in place. To install a new belt (if required) and re-install the pulley, follow these steps:

1. Loop the drive belt around the dryer drum with the groove side facing the drum. (Try to line the belt up with the wear marks already on the drum from the previous belt).

2. With the tensioner in your left hand, insert the clip end of the idler pulley into the grooves on the dryer bottom casing with the idler wheel pointing to your left. (The grooves are directly in front of the drive motor.)

3. While holding the tensioner in place, insert the belt UNDER the wheel with your right hand and pull it up and over the drive motor pulley.

If this does not explain it well enough, you can also verify by going to repairclinic.com. Click on the Repair Help link and look for the "Dryer Belt Diagrams" link under the Special Features section on the next page. Look for Roper and refer to diagram H.

Replacement parts (if required) can be ordered on line at any of the following websites:

searspartsdirect.com
pcappliancerepair.com
appliancepartspros.com
repairclinic.com

The part number for a replacement belt is 341241. All these sites offer great service with competitive pricing, so shop and compare. The first three sites I have listed also inlcude helpful exploded view diagrams that can help you locate and properly indentify the parts you may need.

NOTE: If you still have the teflon glide type tensioner, Whirlpool recommends you replace it with a conventional roller type idler pulley. The teflon type tensioners caused premature wear to the drive belt. The part number is 691366.


Once you have the belt installed, re-install the dryer front panel by holding it as you did previously. Line up the holes on the inside bottom edge of the front panel with the small mounting cleats on the front edge of the side panels. This can be done by yourself, but an assist may make it easier. Once you have the front panel in place, lean against it to hold it in place and install the mounting screws.

NOTE: Don't forget to reconnect the grounding wire and door switch connector plug. Without the door switch connected, the dryer will not run. Lower the top panel back in place and reinstall the two screws.

NOTE: Placing a piece of duct tape over the dryer vent chute will help safeguard against dropping anything down in the blower fan assembly. If you drop any screws down the chute, you will need to remove the dryer back panel to retrieve them.

If the dryer stopped working altogether ( no heat, no drum rotation, no power, etc.), I would recommend you begin by checking the THERMAL FUSE. The fuse is located on the air blower assembly and is a small plastic looking component with two wires attached. Make sure you UNPLUG the dryer before servicing and make sure you take any resistance readings with the component removed from the circuit. You can isolate it by simply unplugging the wires to it. A good reading will be something close to zero ohms.

The following link can give you some added advice on how to troubleshoot a dryer:

http://www.fixya.com/support/r3574266-thorough_dryer_advice


If you do find the thermal fuse blown, it generally blows for a reason. This is usally attributed to something coming in contact with the fuse wires (like loose change from your pockets), or a dryer that has an obstructed exhaust vent. Inspect the interior cabinet and air blower fan for accumulations of dirt or lint, followed by an inspection of the dryer vent from where it leaves the back of the dryer, to where it exits your home. If the dryer exhaust vent is kinked or clogged, the dryer heating circuits will overheat to the point of failure. Failure to provide good air flow for the dryer will results in repeated component failures and can become a fire hazard.

If you have questions, please post back and let me know. I hope you find this information helpful.

My dryer quits working after a period of time, how


You have a motor going bad . Thermostats only control the heat . Replace the motor and that should take care of the problem .

Dryer is making loud thumping noise.


Take off the back panel of the dryer and look at the motor and belt turning the drum. There may be something caught on the drum and is pinned in place causing the noise. The motor could be loose on the platform and needs to be tightened. It is probably something physical and seen causing the noise.

If it doesnt run at all its nothing to do w the thermal aspects at all. The motor would run regardless just no heat. Check all paths electrically to the motor and be sure to check the motor itself.
